Compression chk on cylinders is 150 for the front 3, 135 for back one, leaked down 30 lbs in 10 minutes. Is there a way to isolate the leak prior to tearing engine apart? If the block is cracked, is it repairable? The engine did start and run ok, just lots of bearing noise. Thank you for any help you can offer, Fred [Reply]   [No Email]

I have hardly any money into this tractor so far. Good tires, sheetmetal and loader, so worth putting a little effort into. Not to mention a good excuse for my 17 year old and I to work together. Tried some sealant from NAPA, and it stopped the leak while running. Ran into the pan while parked for several months. We will pull the head and see what's there. Thank you again and MERRY CHRISTMAS.

The big bushing only has a wall thickness of about a sixteenth of an inch. A loader can make that bushing look sad in a hurry. I agree with all said by Aaron Ford. [Reply]  [No Email]

From the leakdown, I'd go on the assumption it's a head gasket, and hope the head's not cracked. Gotta pull it. [Reply]  [No Email]

O rings are used to seal the sleeves. The block can crack between the cylinders but mine wasn't. It sounds like you have a cracked sleeve. The sleeves come with the rebuild kit.

I would remove the head, clean both the head and block mating surface as clean as you can get them. I use a Scotchbrit pad and a a high speed rotory tool to get all debris off the surface. Then I use a three part dye penetrant spray to find the crack. Depending on the crack, it may be repairable. If so, I'ld probably repair it and rebuild the engine, but it's up to you. From the sounds of it though, you will have to do an engine overhaul. Are you fairly proficient welding? You may be able to weld it with nickle rod. Of Course you'll have to file it down real steady afterward. [Reply]  [No Email]

You can also do that to see if it is coming from around one of the piston as in a head gasket leak [Reply]  [No Email]
